HIGH VELOCITY IMPACT TEST

The High Velocity Impact test is designed to ensure protection from high speed, low mass projectiles. An example would be getting hit by gravel from the road while riding a motorcycle. Lenses are shot with a steel ball from straight on and various angles. To pass the High Velocity Impact test, no contact between the lens and eye is permitted; nor may any parts or fragments be ejected from the lens that could contact the eye.

Projectile Specification
Diameter: 1/4"
Composition: Solid Steel
Velocity: 150 feet per second (102 mph)

HIGH MASS IMPACT TEST

The High Mass Impact test is designed to ensure protection from relatively heavy objects travelling at low speeds. An example would be getting hit by the top of a ski, or hitting a branch while mountain biking. A pointed projectile is dropped from a height of 130cm (51.2") onto a lens. To pass the High Mass Impact test, no parts or fragments may be ejected from the lens that could contact the eye.
